,Cleaning Fundamentals & Procedures
Q1. What is the primary purpose of a custodian's daily cleaning routine in a public facility?
A. Improve the appearance only
B. Reduce soil, contaminants, odors, and health hazards
C. Eliminate the need for maintenance staff

D. It prevents chemical exposure
Answer: B. Residue can remain on surfaces and increase cleaning problems
Rationale: Overuse can leave residue, damage surfaces, create slippery conditions, and
increase exposure.
Q6. What is the best general method for removing a fresh liquid spill?
A. Ignore it until the scheduled cleaning period
B. Spread it across the entire floor
C. Secure the area and promptly clean the spill
